Metal tubing differs from metal pipe in the way it is dimensioned. Tubing is specified by OD and wall thickness, whereas pipe is specified by a non-dimensional nominal pipe size (NPS) and a schedule. (SCH) Metal tubing generally has much thinner wall than pipe and can be bent, although both of these depend on the specific application.
